I keep hearing horror stories of people's guests making off with their cards or the money being emptied out of cards by their own guests (wow!!). The coordinator at my venue said it just happened to one of her brides recently and they think it was a down-on-his-luck extended family member. How sad!
I've heard to look for boxes that are closed or locked. Did anyone use a birdcage? Does this seem "closed" enough to keep things safe? Obviously I trust our guests, but hell, you never know!!
